EFFECT OF INTERACTION BETWEEN P-FERTILIZATION (IN MINERAL OR BIO-FORM) AND FE-FOLIAR APPLICATION ON YIELD, CHEMICAL COMPOSITION AND SEED PRODUCTION OF SNAP BEAN PLANT(Phaseolus Vulgaris L.)
Two field experiments were conducted during two successive summer seasons of 2003 and 2004 at El-Baramoon Experimental Farm; near El-Mansoura city; Dakahleya Governorate; Egypt to study the effect of P-fertilizer in mineral or bio-form and Fe-EDTA in foliar way on chemical composition, yield and its component for Nebrasca cv. of snap bean plant (phaseolus vulgaris L.). 16 treatments were arranged in a complete randomized design plot with 4 replicates, P2O5-levels 0,30,60 and 90 kg/fed. were studied in the presence or absence of phosphate dissolving bacteria (PDB) inoculation and Fe-EDTA (300 ppm) in foliar way. Obtained results can be summarized as follow: 1- Application of P-levels solely tell the rate of 60 kg P2O5/fed. significantly increased P-content in the leaves of snap bean plant; increasing the rate of P2O5 up to 90 kg/fed. led to a depressive effect in the same character. On the other hand, P-content in snap bean stems significantly increased at any level of P-fertilizer under study. 2- Fe-content in snap bean plant tended to decreases in the leaves and increases in the stems as the level of P2O5 was increased. 3- The contents of P and Fe in the parts of snap bean plant has been reflected on the values of P/Fe ratio which were increased in the leaves and decreased in the stems as the level of P-addition solely was increased. 4- (PDB) inoculation for the seeds of snap bean plant grown under the levles of P2O5 0, 30 and 60 kg/fed. led to an increase in the contents of P and Fe in the parts of the plant than those obtained for the same levels of P2O5 solely. Increasing the rate of P2O5 from 60 to 90 kg/fed. had a depressive effect on the activity of (PDB). 5- Adding of Fe in foliar way for the plants treated with P levels under study either with or without (PDB) inoculation has been corrected the depressive effect of heavy phosphorus application. Then, P/Fe ratios tended to constant in the leaves of snap bean plant which led to increasing in the yield of snap bean plant.
